ABOUT THIS IMAGE:
This plot compares the colors of solar system planets to the color of the hot-Jupiter-class planet HD 189733b. With the exception of Mars, the colors are primarily determined by the chemistry of the planets' atmospheres. Earth's blue atmosphere plus the blue tint of the oceans dominate our world's hue. HD 189733b's deep blue color is produced by silicate droplets, which scatter blue light in the 2,000-degree-Fahrenheit atmosphere.
